Alan, u have a point about it being in a "bad line of sight", thats true.but my bro is happy ,he's got a cd player that works, so i don't care
As for cutting the dash of an ra40.. how gives a s**t!!the cars worth like $500!
As for setup, man 6inchers in the doors, the 4" fit in the back ontop near the rear seats. i have made a box with 6x9s in the back and it sounds alright.
If the hole is where the factory radio is then just do exactly what chuckster discribed. (i was mearly offer an alternative for if the hole was cut where the tape deckes goes.)
